Fragment is not being replaced after click in navigation drawer

I tried every way to solve this problem but still I am not getting whats wrong with this code. Can you help me?
My mainpage activity is as
import android.support.annotation.NonNull;

public class MainPage extends AppCompatActivity {
private DrawerLayout mDrawerLayout;

super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main_page);

setSupportActionBar(toolbar);
mNavigationView=findViewById(R.id.idnav_view);
ActionBar actionBar=getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeAsUpIndicator(R.drawable.ic_menu);
mDrawerLayout=findViewById(R.id.iddrawer_layout);
mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
Fragment frag=null;
int itemId=menuItem.getItemId();
if(itemId==R.id.id_nvHome){
frag=new HomeFragment();
}
else if(itemId==R.id.id_nvSearch){
frag=new SearchFragment();
}
Toast.makeText(getApplicationContext(),menuItem.getTitle(),Toast.LENGTH_SHORT).show();
if(frag!=null){
FragmentTransaction transction=getSupportFragmentManager().beginTransaction();
transction.replace(R.id.idcontent_frame,frag);
transction.commit();
mDrawerLayout.closeDrawers();
return true;
}
return false;
}
});
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
mDrawerLayout.openDrawer(GravityCompat.START);
return true;
}
return super.onOptionsItemSelected(item);

}
and for mypage activity layout is

}
and also layout for that is as
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

</FrameLayout>
I want to REPLACE FRAGMENT WITH OTHER FRAGMENT WHEN I CLICK ON NAVIGATION DRAWER ITEMS
Can anyone help me?

I can support you giving you my working code for Android 27.1.1:
public class MainActivity extends AppCompatActivity implements
BottomNavigationView.OnNavigationItemSelectedListener {
private int mSelectedId;
/**
* Create Navigation bar and load the main fragment "statistics".
*/
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
loadFragment(new FragmentStatistics());
BottomNavigationView navigation = findViewById(R.id.navigation);
navigation.setOnNavigationItemSelectedListener(this);
mSelectedId = navigation.getSelectedItemId();
}
/**
* Checks for any event in the Navigation Bar.
* If the item selected is the same as the actual item
* Do nothing
* Else
* Load new fragment selected.
*/
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
Fragment fragment = null;
if (mSelectedId != item.getItemId()) {
mSelectedId = item.getItemId();
switch (item.getItemId()) {
case R.id.statistics:
fragment = new FragmentStatistics();
break;
case R.id.shops:
fragment = new FragmentShops();
break;
}
}
return loadFragment(fragment);
}
private boolean loadFragment(Fragment fragment) {
//switching fragment
if (fragment != null) {
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.fragment_container, fragment)
.commit();
return true;
}
return false;
}
}
The rest of your code is exact as mine.

Android Fragment ViewPager Is Recreating Options Menu

I am making an android app which has a navigation drawer with fragments being loaded on navigation items.
One of the fragment is containing two tabs which is loading another two fragments via ViewPager.
Everything is working fine as expectations but the problem comes when I select another navigation item from drawer.
One of the tab has options menu but when I go to another fragment and comes back to the earlier, then options menu gets duplicated.

TABS Are not displayed in Fragment

I am not able to understand why the main fragment is not showing the tabs. My code does not have any errors, its just when I click a item in navigation drawer its not displaying the fragment with tabs.
Can someone please help, thanks for your time, appreciate it.

Please let me know the result.

BEFORE YOU DO ANY OF THIS MAKE SURE YOU HAVE A BACKUP OF YOUR PROJECT AS I HAVE NOT TESTED THIS!!!
INSIDE COORDINATORLAYOUT
Before the fragment_container I want you to place a FrameLayout, make sure it's layout_height is wrap_content. I want you to make it's id equal to realtabcontent. I want you to add the attribute layout_weight to fragment_container and make it equal to 1.
I want you to delete fragment main layout, MAKE SURE YOU HAVE A BACKUP OF THIS PROJECT!!!
INSIDE MAINFRAGMENT
I want you to change onCreateView to:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mTabHost = new FragmentTabHost(getActivity());
mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("fragmentc").setIndicator("Fragment C"), MovieFragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("fragmentb").setIndicator("Fragment B"), GalleryFragment.class, null);

I didn't understand if that actually what you trying to do but as i understood if you want the TextView moves automatically in one line to show the rest of it make this:
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:freezesText="true"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:singleLine="true" />
and in code after defining it's view make this:
textView.setChecked(true);

how to create 2 swipe tabs in fragment?

Hi guys, I have a very big problem and I really don't know where I were wrong.
my app contains Navigation Drawer menu and i need to create swipe tabs in fragments_accounts.xml
Navigation Drawer Menu contains "Accounts" when it's clicked fragments_accounts.xml will show and i wanna create 2 swipe tabs in it.
I changed import android.support.v4.app.Fragment; to import android.app.Fragment; in both of the AccountsFtagmets.java and MainActivity.java
This error will show:
Error:(88, 28) error: incompatible types: AccountsFragment cannot be
converted to Fragment
How can i rescue from this error??
it's killing me!!!

if (fragment != null) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.container_body, fragment);
fragmentTransaction.commit();
// set the toolbar title
getSupportActionBar().setTitle(title);
}
}
}
Thank You.

Your AccountsFragment needs to extend Fragment not FragmentActivity.
